Communication functions

The RET 54_ transformer terminal provides the IEC_103, Modbus
and LON serial communication protocols.
In a customer-specific transformer terminal configuration, special events can be
generated via an EVENT230 event function. EVENT230 is documented on the CD-
ROM "Technical descriptions of Functions" (refer to "Related documents" on
page 9).
For more information about communication in the RET 54_ transformer terminal,
refer to Section "Serial communication" on page 69.
